Green building (also known as green construction, sustainable building, or eco-friendly building) refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation between the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature. Buildings that live in harmony; green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization.

Leadership in Energy and Environmental Design (LEED) is a set of rating systems for the design, construction, operation, and maintenance of green buildings, developed by the U.S. Green Building Council. Other certification systems that confirm the sustainability of buildings are the British BREEAM (Building Research Establishment Environmental Assessment Method) for buildings and large-scale developments or the DGNB System (Deutsche Gesellschaft für Nachhaltiges Bauen e.V.) which benchmarks the sustainability performance of buildings, indoor environments, and districts. Currently, the World Green Building Council is conducting research on the effects of green buildings on the health and productivity of their users and is working with the World Bank to promote green buildings in Emerging Markets through EDGE (Excellence in Design for Greater Efficiencies) Market Transformation Program and certification. There are also other tools such as NABERS or Green Star in Australia, Global Sustainability Assessment System (GSAS) used in the Middle East and the Green Building Index (GBI) predominantly used in Malaysia.

Leadership in Energy and Environmental Design (LEED) is a green building certification program used worldwide. Developed by the non-profit U.S. Green Building Council (USGBC), it includes a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods, which aims to help building owners and operators be environmentally responsible and use resources efficiently.

As of 2024 there were over 195,000 LEED-certified buildings and over 205,000 LEED-accredited professionals in 186 countries worldwide.In the US, the District of Columbia consistently leads in LEED-certified square footage per capita, followed in 2022 by the top-ranking states of Massachusetts, Illinois, New York, California, and Maryland.Outside the United States, the top-ranking countries for 2022 were Mainland China, India, Canada, Brazil, and Sweden.LEED Canada has developed a separate rating system adapted to the Canadian climate and regulations.

The Green Business Certification, Inc. (GBCI) is an American organization that provides third-party credentialing and verification for several rating systems relating to the built environment. It was established as the Green Building Certification Institute in January 2008 with the support of the U.S. Green Building Council to provide independent oversight of the Leadership in Energy and Environmental Design (LEED) project certification and professional credentialing processes. The organization's current name was adopted on 16 April 2015 after the organization began to provide third-party certification for the International WELL Building Institute's evidence-based building standard WELL Building Standard, the Perfect Power Institute's PEER standard, and the Global Real Estate Sustainability Benchmark.

The economy of Bangladesh is considered to be a major developing mixed economy. As the second-largest economy in South Asia, Bangladesh's economy is the 34th largest in the world in nominal terms, and 25th largest by purchasing power parity. Bangladesh is seen by various financial institutions as one of the Next Eleven. It has been transitioning from being a frontier market into an emerging market. Bangladesh is a member of the South Asian Free Trade Area and the World Trade Organization. In fiscal year 2021–2022, Bangladesh registered a GDP growth rate of 7.2% after the global pandemic. Bangladesh is set to graduate from the group of least developed countries and will join the group of developing countries in November 2026.

Industrialisation in Bangladesh received a strong impetus after the partition of India due to labour reforms and new industries. Between 1947 and 1971, East Bengal generated between 70% and 50% of Pakistan's exports. Modern Bangladesh embarked on economic reforms in the late 1970s which promoted free markets and foreign direct investment. By the 1990s, the country had a booming ready-made garments industry. As of 16 March 2024, Bangladesh has the highest number of green garment factories in the world with Leadership in Energy and Environmental Design (LEED) certification from the United States Green Building Council (USGBC), where 80 are platinum-rated, 119 are gold-rated, 10 are silver, and four are without any rating. As of 6 March 2024, Bangladesh is home to 54 of the top 100 LEED Green Garment Factories globally, including 9 out of the top 10, and 18 out of the top 20. As of 27 April 2024, Bangladesh has a growing pharmaceutical industry with 12 percent average annual growth rate. Bangladesh is the only nation among the 48 least-developed countries that is almost self-sufficient when it comes to medicine production as local companies meet 98 percent of the domestic demand for pharmaceuticals. Remittances from the large Bangladeshi diaspora became a vital source of foreign exchange reserves. Agriculture in Bangladesh is supported by government subsidies and ensures self-sufficiency in food production. Bangladesh has pursued export-oriented industrialisation.

The Trustees of Reservations (also referred to as Trustees or The Trustees after a 2021 rebranding) is a non-profit land conservation and historic preservation organization dedicated to preserving natural and historical places in the Commonwealth of Massachusetts.

In addition to land stewardship, the organization is also active in conservation partnerships, community supported agriculture (CSA), environmental and conservation education, community preservation and development, and green building. The Trustees owns title to 120 properties on 27,000 acres (11,000 ha) in Massachusetts, all of which are open to the public. In addition, it holds 393 conservation restrictions to protect an additional 20,000 acres (8,100 ha).
